Description: A device, usually a weatherproof encasement commonly made of tough plactic used to protect the exposed area between spliced cables or fibers.
Description: The Riser feature class is used in 3-GIS to denote the transition of a fiber cable from underground/buried to aerial. If a user is tracking the placement type of a cable, aerial vs underground/buried, there must be two separate fiber cables created to represent each distinct placement type. The Riser feature class allows the signal or light from one cable to pass into the other cable much like a splice closure. In addition, the height attribute on a riser can be populated to denote the elevation change from the underground/buried cable to the aerial cable up on the pole. This height is then added to the length of the overall signal or light path.
Description: A cable that is constructed of an inner core of optical fibers (glass or plastic) which are covered by high-density polyethylene. Fiber cable may be wrapped with various types of strengthening materials including steel wire and high-density polyethylene. Optical fiber consists of a core and a cladding layer, selected for total internal reflection due to the difference in the refractive index between the two. In practical fibers, the cladding is usually coated with a layer of acrylate polymer or polyimide.
Description: The Conduit feature class is a linear feature class that can be used to track the placement of conduit which are used to house fiber cables. The Conduit feature class does not allow for the tracking of sub ducts or micro ducts or duct connectively typically seen in a blown fiber network. Sub duct tracking, duct connectivity and blown fiber infrastructure is supported using the Span feature class. The Conduit feature class can be used to track what fiber cables are in a given conduit.
